I've heard the L98 IROCs were much faster than the 5.0L Stangs. Did your '88 have the L98 or the LB9?

Maybe in 1987 when they came out . They were a solid mid 14's car . Heck my 305 5 speed ( 3.08 LSD)banged of 15.1 and the tranny was shot and the motor pissing oil out

The L-98's were right on par with the little 5.0L mustangs . Remeber how light they were( Mustangs).... thats half of it right there . Put the L-98 in the Mustang and see what it does with that .

Yeah, the Mustangs probably weighed around 3100 lbs, if that....

The lt1 was way more impressive than the l98's. l98's are tq'y down low but had noting up top.

I understand what you're saying about the L98 losing power, but I think we're each "missing the beat" with what each other is saying. I'm not disagreeing with you that the LT1 makes more power up top, but what I'm questioning is that maybe the L98 isn't the problem at all with it falling flat on its face, and it's the 700R4 that's not optimized.....
